## What it is
A Language Server Protocol implementation and toolchain for Postgres SQL, built on libpg_query for 100% syntax compatibility. It provides editor features like autocompletion, hover, diagnostics, type checking, formatting, and linting via LSP, CLI, HTTP APIs, and a WebAssembly module.

## Use cases
- get SQL autocompletion and hover docs in my editor for Postgres
- lint Postgres migrations for unsafe changes
- type-check SQL queries against a live database
- format SQL files consistently
- catch syntax errors in PL/pgSQL functions while editing
- integrate Postgres SQL diagnostics into Neovim or VSCode

## When to choose
- you write or maintain Postgres SQL and want IDE-grade tooling
- you need migration or database linting in CI
- you want a parser-accurate SQL formatter or diagnostics via LSP

## When to avoid
- you work with non-Postgres databases like MySQL or SQLite
- you need a full SQL IDE or query GUI rather than editor tooling

## Facets
- artifact type: library
- maturity: active
- function: linter, formatter, parser, developer-tools, editor
- domain: databases, developer-tools, parsers, apis
- platform: cross-platform, editor-plugin, cli, wasm
- tags: postgres, language-server-protocol, sql, lsp, rust, type-checking, autocompletion, migration-linting
